SAS Expander HP Enterprise DL38X Gen10 12Gb - Hewlett Packard Enterprise

SAS Expander HP Enterprise DL38X Gen10 12Gb is a backplane expansion module compatible with Hewlett Packard Enterprise DL38X Gen10 servers. It provides 12Gb/s SAS connectivity to increase storage port density and enable connection of additional disk enclosures or direct-attached drives through the server backplane. The component is intended for enterprise and data center environments where reliable SAS performance and scalable device connectivity are required.

Advantages

The SAS expander increases available SAS ports without requiring additional host bus adapters, allowing administrators to scale storage capacity within an existing server chassis. With 12Gb/s link speeds, it supports high-throughput data transfer and is compatible with standard SAS devices that operate at matched link rates. The module is designed for integration with the DL38X Gen10 backplane to maintain signal integrity and consistent device enumeration when adding external or internal enclosures.

Suitable for

• Expanding direct-attached storage in HP Enterprise DL38X Gen10 servers
• Increasing drive bay connectivity for dense server configurations
• Data center deployments requiring additional SAS device connections
• Server maintenance and storage infrastructure upgrades

Key specifications

• SAS link speed: up to 12Gb/s per lane
• Form factor: server backplane expander module designed for DL38X Gen10 chassis
• Function: expands SAS port count and enables attachment of additional enclosures or drives
• Compatibility: designed to work with the DL38X Gen10 server backplane and typical SAS storage devices
• Use environment: enterprise and data center storage applications

How to use

Install the SAS expander into the designated expansion slot or backplane connector inside the DL38X Gen10 server following the server manufacturer's service and installation instructions. After physical installation, verify cabling between the expander and target enclosures or drives, ensuring SAS cables are rated for 12Gb/s where required. Power on the server and attached enclosures, then confirm that the operating system or RAID controller recognizes newly connected devices and that device enumeration matches expected port mapping. Perform firmware compatibility checks and update expander or backplane firmware if recommended by Hewlett Packard Enterprise.

Usage recommendations

Use certified SAS cables and follow the server chassis airflow and cooling guidelines when adding additional enclosures. For consistent performance, match device link rates where possible and follow HPE guidance for firmware and controller compatibility to avoid drive discovery or performance issues.
